track, and its object-s to pr jvde a novel end improved truck end wheel construction which eflectually prevents any tendency of the wheels to spread end cause looseness end ultimate collapse of l;he ca1riel frame supported by the wheels.

The object stated is attained by the con struction to be described in detal hereinufter, and in order that the same 1nay be better understood, reference s had to the accompanyng drawng, wherein Figure 1 s av perspectve view of the track, and

Fig. 2 is -an end view of the tra-ok end a 'ragment of the carrier mounted thereon.

Referring specifically to the drawng, the track me1nber or rail is made substantia,lly cruciform in cross-secton to obta in outstandng tread flanges 5 on opposite sides of a median web having an upstandng upper portion 6 projeeting above the flanges, end a depending lower portion 7 projecting be1ow said flanges. The top of the web porlzion 6 is formed with a head8,- and the bottom of the web portion 7 has a head 9. These heads are provided for the attachment of the brackets whereby the track s suspended fro1n an overhead support, and it w1l be noted that they difler in shape, which is for the purpose of assuring that the track be properly mounted t-o postion the tread surfaces of the flanges 5 on top. The bracket members carrying the t1ack Will be made to correspond to the shape of the heads, end hence t Will be impossible to mount the truck wrong or in inverted positon.

The top 01 tread surface 10 of each flange 5 is made flat, and with 2m inward and dwnwnrd slope, and the wheels of the carrier are made to conform to this surface., The wheels are arranged in pairs, one wheel being mounted on oneflange 5 and the othe1. wheel beng oppostely disposed end mounted v on the other flange 5. Each wheel is composed of a tread portion 11 and a flange 12 'at one end thereof, said flange being located alongside the edge of the flange 5. The tread portion 11 of the wheel has the shape of' a frusto-conical roller, the flange 12 beng at the smaller end. Ths shape of the tread portion 11 of the wheels adapts the same to the nWardly inclined tread surface 10 of the flanges 5, end counteracts any spreading tendency of the wheels, the inclined surfaces constantly urging the wheels nwardlytoward each other rather than outwardlyor away from eaoh other. The structure therefore efi'ectually prevents the currier frame from gettng loose Which is very often the case where the track is so const-rncted thut it does not counteract the spreading tendency of the wheels.

1. A track member comprising a medial vertical web and flanges projecting horizontally from opposite sides thereof, the top of each flange having a flat tread surface Which slopes clownwardly n the direction ci che web 521161 Web projectmg above and below the flanges, and its extremites being prov'ded with heads, the head of one web projection beng shaped dfferently fro1nthe head of the other web projecton.

2. T he combiflation of oppositely located wheels, end a track for supporting said wheels, said trak havng a supporting flange for each wheel, the tread surface of said flange beng flat end havng a downward end inward slope, and each wheel having a tread portion which is frusto-conical to seat on and conform to che aforesaid slopng trend surface of the flange.

8. The combnation of oppositely located wheels, and a track for supporting said wheels, said track having a supporting flange for each wheel, the tread surface of said flange being flat end having a downward end. inwa1d slope, and each wheel baving a treed portion which is fiusto-conical FREDERIC P.
